Circuit 1

Got stuff warmed up with a simple regulator circuit. LM317 for variable output, LM7812 for 12V, LM7805 for 5V. Running off a small 13.8 VDC supply.

This will be useful when I decide to mess with discrete transistor circuits. I need to mount it on standoffs. I'm in no hurry, I want to mess with tubes first. Waiting on some circuit board sockets, should be here this week.
